The frequency and severity of extreme fires have nearly doubled in the past 20 years. This alarming conclusion comes from a study published in the journal Nature Ecology & Evolution, conducted by scientists from the University of Tasmania. Led by Calum Cunningham, the team analyzed satellite data from 2003 to 2023 to identify hotspots and assess the overall intensity of fire events, rather than focusing on individual incidents.

According to the experts, since 2017, there have been six years with the most extreme fire events, which have resulted in significant losses of human lives, property, livestock, wildlife, and habitats. Fires cause billions of dollars in damage, not only during the events but also due to the resulting air pollution. The study found that the frequency and intensity of highly energetic fires have more than doubled in the last 20 years, with the six most extreme years occurring since 2017.

The research also revealed that the Nearctic and Australia/Oceania regions were the hardest hit, with most extreme events occurring in coniferous and boreal forests, including those in North America and Russia. The researchers suggest that this trend may be partly due to increased aridity in these environments, primarily driven by climate change. These findings underscore the urgent need to adapt to a climate that increasingly favors such extreme fire events.
